Psychometric properties of a 21st century digital skills scale

Abstract

To prepare students to cope successfully with increasingly complex life and work environments based upon the extensive application of information-communication technology (ICT), today’s education should focus on cultivating 21st century digital skills. To assess the extent to which these ICT-based skills have been attained, an appropriate scale with good psychometric properties needs to be applied. By using a sample of 667 teachers from about 200 secondary schools across Serbia, this study examined the psychometric properties of a 21st century digital skills scale. These properties dealt with representativity, reliability, homogeneity, and validity. The examination showed that this scale was of a good quality for each of these properties. Suggestions for further research are included.
